Vortex ADR-X-30 Cantilever Quick-Release Ring Mount 3-Inch

Similar to the ADR, the ADR-X mount is designed for mounting telescopic sights for 30mm tubes onto a flattop style AR-15 rifle. The 3-inch offset of this cantilever mount positions the scope in a forward location, allowing the correct eye relief and head placement on an AR-15. The extended 3-inch cantilever on the ADR-X provides an extra inch of offset compared to the ADR model and is best suited for scopes with four inches or more of eye relief.
